Description

A kind of bottom flexible post energy-eliminating shock-insulating structure
[technical field]
The utility model relates to the technical field of building structure technical field of isolation, particularly energy-eliminating shock-insulating.
[background technology]
The shock insulation of building structure and energy-dissipating and shock-absorbing have been widely used in Practical Project, and it reduces the effect of earthquake to structure by flexible isolating and damping energy dissipation, has good damping effect.The isolation energy dissipation method mainly Base Isolation Technology that current application is more, it carrys out the natural vibration period of extending structure by installing shock isolating pedestal between superstructure and basis, and passes through the Damping work seismic energy of bearing, greatly can reduce earthquake potential damage.
Traditional isolation structure arranges shock isolating pedestal or sliding and shock isolation bed course between basis and superstructure, and need to arrange the thicker beam and slab type superstructure of one deck on Seismic Isolation of Isolation Layer top, this will significantly increase cost and the difficulty of construction of structure, thus make the popularization of Base Isolation Technology be restricted.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of bottom flexible post energy-eliminating shock-insulating structure.The utility model does not need to install shock isolating pedestal, by the natural vibration period of the distortion extending structure of structure bottom flexible column, and imported into the seismic energy of structure by the dissipation of mild steel element for energy dissipation, utilize close rib infilled wall and positive stop to carry out Bit andits control simultaneously, ensure the stability of structure bottom, the effect of shock insulation and damping can be played structure.
For achieving the above object, the utility model proposes a kind of bottom flexible post energy-eliminating shock-insulating structure, be made up of steel core concrete column, close rib infilled wall, superstructure, S shape mild steel plate, positive stop, shown close rib infilled wall is formed by waffle beam, close rib post and concrete block masonry.Described steel core concrete column supports superstructure, and is connected by S shape mild steel plate with between close rib infilled wall; The floor beam of described superstructure is also connected by S shape mild steel plate with between close rib infilled wall; Between described close rib infilled wall and the floor beam of steel core concrete column and superstructure, prearrangement of deformation amount stitches.Described S shape mild steel plate and steel core concrete column adopt and are welded to connect, and close rib post, the beam of superstructure, between waffle beam by pre-buried anchoring.
As preferably, the slenderness ratio of described steel core concrete column is no more than 50.
As preferably, the building block of described close rib infilled wall adopts porous brick.
As preferably, the width of described close rib post, waffle beam is identical with the thickness of close rib infilled wall.
As preferably, the yield strength of described S shape mild steel plate is no more than 160MPa.
As preferably, the longitudinal steel ratio values of described waffle beam, close rib post is not less than 0.2%.
As preferably, described positive stop and waffle beam, superstructure beam is cast-in-place forms.
The beneficial effects of the utility model: the utility model utilizes the feature of concrete filled steel tube post high-strength and high flexibility, it can be used as the base layer support of structure, play the effect of shock insulation.Do not need to use shock isolating pedestal, do not need the beam and slab structure increasing Seismic Isolation of Isolation Layer yet, save engineering cost and reduce difficulty of construction.By building close rib infilled wall by laying bricks or stones at bottom, and adopt S shape mild steel plate to consume energy, the effect of earthquake to structure can be reduced further.By arranging positive stop between close rib infilled wall and the beam of superstructure, when can prevent earthquake, displacement is excessive and collapse.Compare with sliding base isolated with neoprene bearing shock insulation, there is stronger tensile property, good self-resetting capability and energy consumption effect.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the generalized section of a kind of bottom flexible post of the utility model energy-eliminating shock-insulating structure.
In figure: 1-steel core concrete column, 2-close rib infilled wall, 3-superstructure, 4-S shape mild steel plate, 5-waffle beam, the close rib post of 6-, 7-positive stop.
[detailed description of the invention]
Consult Fig. 1, the utility model comprises steel core concrete column 1, close rib infilled wall 2, superstructure 3, S shape mild steel plate 4, waffle beam 5, close rib post 6, positive stop 7.Described close rib infilled wall is built by laying bricks or stones formed by building block, waffle beam, close rib post entirety.The upper end of described steel core concrete column 1 is anchored in superstructure 3, is connected between its side with close rib infilled wall 2 by S shape mild steel plate 4; The floor beam of described superstructure 3 is also connected by S shape mild steel plate 3 with between close rib infilled wall 2; Shown between close rib infilled wall 2 and the floor beam of steel core concrete column 1 and superstructure 3 prearrangement of deformation amount stitch; Described S shape mild steel plate 4 and steel core concrete column 1 adopt and are welded to connect, and close rib post 6, the floor beam of superstructure 3, between waffle beam 5 by pre-buried anchoring; Described positive stop 7 is between close rib infilled wall 2 and the floor beam of superstructure 3.
Utility model works process:
The earthquake isolation principle of a kind of bottom flexible of the utility model post energy-eliminating shock-insulating structure is: steel core concrete column 1 has larger flexibility and elasticity, the natural vibration period of total is extended, avoids seismic predominant period; The lateral rigidity of superstructure is relatively large, and the lateral rigidity of bottom steel core concrete column is less, and during earthquake, the relative storey displacement of structure mainly concentrates on bottom; Dissipated by S shape mild steel plate 3 simultaneously and import the seismic energy of structure into, and utilize the larger lateral rigidity of close rib infilled wall 2 and positive stop 7 pairs of structures to carry out Bit andits control.
The utility model can play the effect of shock insulation and energy-dissipating and shock-absorbing, and when can prevent again earthquake, displacement is excessive and collapse, and has good damping effect and resistance to capsizing; Do not need shock isolating pedestal is installed, do not need to increase the beam and slab structure of Seismic Isolation of Isolation Layer yet, can engineering cost be saved and reduce the difficulty of construction of isolation structure.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
